"We believe more centers are applying for AASM accreditation as more patients are beginning to understand the consequences of sleep illness. They're looking for help," Dr. Sam Fleishman, M.D., the president of the AASM, said in a statement.

At sleep centers, people can have their sleep problems evaluated by a board-certified sleep medicine doctor. Common sleep problems evaluated at these facilities include sleep apnea, which is when a person stops breathing momentarily during sleep, and insomnia, which is when a person cannot sleep during the night and is sleep-deprived.

Sleep Paralysis

If you've ever drifted off to sleep or just woken up from sleep but were unable to move any part of your body -- spurring a sense that you are frozen in your bed -- you may have experienced sleep paralysis.
Sleep paralysis is more common in the seconds to minutes when we're first waking up, whether in the morning or in the middle of the night, Gehrman said.
When we are in REM sleep, our muscles are paralyzed so that we don't act out our dreams. But with sleep paralysis, a part of the brain wakes sooner than the rest, giving a sense of wakefulness and alertness -- even though the body's muscles are still paralyzed, Gehrman explained.
However, <a href="http://www.stanford.edu/~dement/paralysis.html" target="_hplink">sleep paralysis isn't dangerous</a> despite the unsettling feeling experienced by people who have been through it, according to Stanford University. To decrease the number of sleep paralysis episodes you have, stress reduction, getting enough hours of sleep a night and making sure you have a good sleep schedule could help.
